Should I be concerned with the gems for running vagrant?
➜ ~ vagrant version
Ignoring nokogiri-1.6.3.1 because its extensions are not built. Try: gem pristine nokogiri --version 1.6.3.1
Ignoring unf_ext-0.0.7.1 because its extensions are not built. Try: gem pristine unf_ext --version 0.0.7.1
Installed Version: 1.9.0
Latest Version: 1.8.7
You're running an up-to-date version of Vagrant!
➜ ~ gem pristine nokogiri --version 1.6.3.1
ERROR: While executing gem ... (Gem::Exception)
Failed to find gems ["nokogiri"] = 1.6.3.1
➜ ~ gem pristine nokogiri --version 1.6.3.1

I experienced this after upgrading to MacOS 10.2.2 and Vagrant 1.9.1. I'm not sure which caused this issue.
Based on info at https://groups.google.com/forum/#!topic/vagrant-up/z6GX-3Qn3ZM I used the uninstaller script and then re-installed Vagrant and I stopped seeing these 2 lines.
